From 440b87eac4ca21ccb3f56e7b1f126e0eebcc0f84 Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Thu, 6 Feb 2014 11:45:12 -0500 Subject: [PATCH] drivers/net: fix build warning in ethernet/sfc/tx.c Commit ee45fd92c739db5b7950163d91dfe5f016af6d24 ("sfc: Use TX PIO for sufficiently small packets") introduced the following warning: drivers/net/ethernet/sfc/tx.c: In function 'efx_enqueue_skb': drivers/net/ethernet/sfc/tx.c:432:1: warning: label 'finish_packet' defined but not used Stick the label inside the same #ifdef that the code which calls it uses. Note that this is only seen for arch that do not set ARCH_HAS_IOREMAP_WC, such as arm, mips, sparc, ..., as the others enable the write combining code and hence use the label.
